Stainless Steel 904l fasteners

What are Stainless Steel 904L Fasteners

Bolts manufactured from 904L stainless steel undergo solution heat treatment in the range of 1090°C and 1175°C and are then rapidly cooled in order to retain their strength and resistance to corrosion. This grade is usually cold-worked prior to the final solution treatment in the case of the maximum protection against stress-corrosion cracking.

The amount of ultra-low carbon in these UNS N08904 threaded rods is 0.02%, and this assists in sustaining structural stability upon welding and exposure to high temperatures. Precisely due to their high resilience against severe acid and harsh media, 904L fasteners are broadly deployed in the harsh industry processes.

Their use is in acetic, phosphoric, and sulphuric acid plants, pipeline networks, gas scrubbers, refinery equipment, seawater cooling systems, heat exchangers, bleaching lines, and other systems used to control pollution. These qualities of 904L screws include their resistance to chloride-rich and corrosive conditions, which are characterised as the favourite of long-term and unproblematic functioning of setups in high-stakes engineering.
